Abstract:
A switch assembly including a vacuum switch mounted to an at least partly electrically conductive housing, and a holder for a vacuum bottle. The housing includes at least one gas entry opening at a lower end of the housing and at least one gas exit opening at an upper end of the housing, and a first free heat convection path between the openings to provide cooling. A second free heat convection path may be provided in a free space between the holder and vacuum bottle. A switching device for connecting the vacuum switch to a second electric conductor. An electric power distribution switchgear, encapsulating at least one three-phase module including a switching device.
